Subject: package/bdwgc: musl build failure
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7df8f06d0864dd90d0c79b0215089cd25f13ff13;p=buildroot.git

package/bdwgc: musl build failure

Fixes http://autobuild.buildroot.net/results/1ed/1edb5e7dab88d3fefca533ab56f7ddc7dd5411d2/

Upstream removed unused code which was causing musl compilation issues.

+Subject: [PATCH 1/1] Do not include sigcontext.h and asm/sigcontext.h (these
+ Linux headers define sigcontext which is no longer used as replaced with
+ ucontext_t in GC 7.0alpha1)
+
+* os_dep.c: Do not include linux/version.h (do not test
+LINUX_VERSION_CODE), asm/signal.h, sigcontext.h, asm/sigcontext.h
+since struct sigcontext not used in GC v7+.
